Description

[Detailed Description of the Invention] The present invention relates to a flush toilet device, and more particularly, to one that can be used as a seat type by placing and fixing a seat body on the top surface of an existing flush Japanese-style toilet.

Conventionally, this type of flush toilet device was developed in 1982.
There is one in Publication No. 13186.

To explain this, one of the water inlets of the ball tap provided in the water storage tank that supplies water directly into the tank, or the water inlet that supplies water into the tank via the hand washing pipe, and the inner peripheral surface of the ball part of the seat body. By connecting the nozzle installed in the toilet bowl with a water supply pipe, cleaning water is discharged from the nozzle to clean the inner peripheral surface of the bowl part, in addition to cleaning the existing Japanese-style toilet bowl.

However, this type of toilet can only be used with Japanese-style toilets whose water supply device consists of a water storage tank with a hand-washing pipe; in the case of other water supply devices, such as a water storage tank without a hand-washing pipe or a flush valve, the secondary There was a problem in that water could not be supplied to the nozzle of the seat body unless a branch pipe was connected to the water supply pipe to separate the water supply pipe for the Japanese-style toilet bowl and the water supply pipe for the seat body.

Therefore, the object of the present invention is to solve the above-mentioned problems and to enable existing Japanese-style toilets to be used as they are, no matter what type of water supply device they are equipped with.

The basic structure of the present invention is to provide a rim passageway with a number of water injection holes for discharging cleaning water toward the inner circumferential surface of the opening edge of the ball part of the seat body, and a drainage channel that communicates with the rim passageway. The existing Japanese-style toilet can be used as a seat-type toilet by forming the rim so that it discharges flushing water toward the saucer part of the Japanese-style toilet, and by connecting the flushing pipe that communicates with the existing water supply direction to this rim passageway. This is how it was done.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In this embodiment, as shown in Fig. 1, a flush Japanese-style toilet A is installed on a stepped floor D, and a seat body B is placed above the Japanese-style toilet A to cover it.
This is what is listed.

The seat body B is made of ceramic or synthetic resin such as FRP and has a shape that covers the upper surface of the Japanese-style toilet bowl A, and the front half of the seat body B is formed into a box shape with an open bottom. At the same time, a water supply chamber 5 is formed in a hollow shape on the upper surface thereof, and a ball part 1 facing the saucer part 21 of the Japanese-style toilet bowl A is opened in the rear half part.

The ball part 1 is formed into a funnel shape along the rear rim 22 of the Japanese-style toilet bowl A, and its lower end opening edge is inserted into the Japanese-style toilet bowl A, and a rim water passage 2 is provided at the upper end opening edge over the entire circumference.

The rim water passage 2 is formed on the upper part of the ball part 1 so as to protrude inward so as to face the inside of the ball part 1, and a number of water injection holes 4 are bored at appropriate intervals on the lower surface thereof, and a number of water injection holes 4 are bored at appropriate intervals. A communication hole 6 communicating with 5 is opened.

Further, a cylindrical drainage channel 3 extending in the height direction is protruded from the rear end of the ball portion 1, and a through hole 7 is bored at the upper end of the drainage channel 3 to communicate with the rim water passage 2. At the same time, the lower end opening 3' is connected to the saucer part 2 of the Japanese-style toilet bowl A.
Protrude to around 1.

A water supply chamber 5 formed on the upper surface of the front half of the seat body B is equipped with a water supply device C, which is a water source for supplying water to the so-called existing flush-type Japanese style toilet bowl A, such as a water storage tank and flush valve, and in this embodiment, a hand washing pipe. The tip of the cleaning pipe 15 connected to the secondary side of the water storage tank without water is connected.

In addition, a mounting hole 8 is drilled in the upper surface of the seat body B, and a toilet seat 9 and a lid 10 are rotatably mounted above the seat 9 as needed in the hole 8, and a pedestal 11 is protruded from the lower end of the outer periphery. and fix this pedestal 11 with screw 12.
etc. to fix it to the floor D.

On the other hand, the Japanese-style toilet A shown in the drawings is of the so-called flushing type, and the water supply port 23 to which the flushing pipe connected to the water supply device C is connected is usually closed off by attaching a lid 24 or the like.

Next, FIG. 3 shows another embodiment, in which a Japanese-style toilet A is installed on a flat floor D, a flush valve is used as a water supply device, and a flushing pipe is installed on the secondary side of the flush valve. 15 are connected.

The seat body B in this case is formed higher than that of the previous embodiment to make it easier to use.

In both of the embodiments described above, the drainage channel 3 is formed in a cylindrical shape extending in the height direction at the rear end of the ball portion 1, but the drainage channel 3 is not limited to this and may be formed in a different shape.

In such a flush toilet device, when a predetermined amount of flushing water is flowed from a water supply device C such as a water storage tank or a flush valve to the water supply chamber 5 of the seat body B through the cleaning pipe 15, the rim is flushed from the communication hole 6. A part of the water flows into the water passage 2 and is discharged from the water injection holes 4 toward the inner circumferential surface of the ball portion 1 to wash away dirt adhering to the surface, and the remaining washing water flows through the water passage 7 to the drainage channel 3. The water flows through the lower end opening 3' and is discharged toward the tray portion 21 of the Japanese-style toilet bowl A, and the waste on the tray portion 21 is discharged through the trap portion 25 to the drain port portion 26.

Therefore, the drainage channel 3 is the saucer part 2 of the Japanese-style toilet bowl A.
The drain channel 3 is formed in such a way that a certain amount of water and water force can be obtained to ensure that the filth on the drain channel 3 can be flushed away to the drain port section 26, and the lower end opening 3' of the drain channel 3 is bent toward the trap section 25 of the Japanese-style toilet bowl A. It is preferable to do so.

Since the present invention has the above configuration, it has the following advantages.

A rim passageway is provided on the opening edge of the ball part of the seat body, and a rim passageway is provided with a number of water injection holes for discharging cleaning water toward the inner circumferential surface of the rim passageway. In addition to being formed to discharge water, the rim water passageway is connected to a cleaning pipe that connects to the existing water supply system, making it possible to easily and inexpensively convert existing flush-type Japanese-style toilets into seat-type toilets. If the water supply device is not a Japanese-style toilet that constitutes a water storage tank with a hand-washing pipe, there is no inconvenience that it cannot be made into a sitting type, and no matter what kind of water supply device the existing Japanese-style toilet is equipped with, there is no problem with branch pipes etc. It can be used as is without using it.

If the seat body covers the front cover of a Japanese-style toilet bowl so that it does not get dirty, it not only looks good, but also saves water used for cleaning the inner surface of the front cover.
